Confidence Analysis
Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 444m, avg 446m) for 45 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

High-confidence STS candidate. Two tankers (STAVANGER STAR and KIMOLOS) maintained close proximity (min 131m, avg 145m) for 129 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (STAVANGER STAR and KIMOLOS) maintained close proximity (min 131m, avg 140m) for 255 minutes. Both vessels were slow-moving (avg speeds 0.1 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (STAVANGER STAR and GAS HUSKY) maintained close proximity (min 437m, avg 444m) for 324 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 438m, avg 444m) for 270 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer.

Confidence Analysis
Low-confidence STS candidate - may warrant review. Two tankers (STAVANGER STAR and GAS HUSKY) maintained close proximity (min 439m, avg 443m) for 36 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (STAVANGER STAR and KIMOLOS) maintained close proximity (min 130m, avg 135m) for 159 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
High-confidence STS candidate. Two tankers (KIMOLOS and STAVANGER STAR) maintained close proximity (min 132m, avg 135m) for 84 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (STAVANGER STAR and KIMOLOS) maintained close proximity (min 136m, avg 189m) for 90 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.5 knots). Moderate distance variation observed during the encounter. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
Low-confidence STS candidate - may warrant review. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 443m, avg 443m) for 36 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 442m, avg 444m) for 189 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.

Confidence Analysis
Moderate-confidence STS candidate. Two tankers (GAS HUSKY and STAVANGER STAR) maintained close proximity (min 442m, avg 444m) for 288 minutes. Both vessels were slow-moving (avg speeds 0.0 and 0.0 knots). The stable separation distance suggests deliberate parallel positioning typical of cargo transfer. Event occurred in Augusta, Sicily STS Zone, a known STS activity area.
